🧪 Example Scenarios

Use these default and higher-pressure example inputs to explore how sensitive this calculator is before using your real numbers.

Input	Base Case	Higher Pressure Case

⚙️ How It Works

Calculates the true long-term financial cost of smoking by combining direct purchase costs with the opportunity cost of the money that could have been invested instead.

The Formula

Total Spent = Packs/Week × Cost/Pack × 52 × Years | Invested = FV Annuity at Return Rate

💡This calculator is scenario-based. Better input quality leads to better decision quality.

Practical Tips

💡 The opportunity cost of invested cigarette money is often far more shocking than the direct spend.

💡 Quitting smoking is one of the highest-ROI financial decisions a smoker can make.

💡 Run a best-case, base-case, and worst-case scenario before deciding.

💡 Use recent real values, not ideal assumptions, for better accuracy.

Frequently Asked Questions

❓ Does this include health care costs?

No. This only models direct purchase costs and lost investment. Healthcare costs from smoking-related illness would increase the true cost dramatically.

❓ What investment return rate should I use?

The US stock market has historically returned ~7% after inflation. This is a reasonable conservative long-term assumption.
